<pre><code>Failed to tune into station: Stations are only available to paying Last.fm subscribers

<p>These are features I've been able to use in both the Last.fm client from the Software Center and the Rhythmbox plugin. I can also go to the website and listen there. What gives?</p>
<p><strong>Update</strong>: To clarify, I have a Last.fm account, but am not a paying subscriber.</p>
<p>Following a <a href="http://blog.last.fm/2009/03/24/lastfm-radio-announcement" rel="nofollow noreferrer">link</a> in the answer provided by <a href="https://askubuntu.com/users/114/dor">DoR</a>, it seems Last.fm changed the structure of their service to be restricted outside of the US, UK and Germany, but I am in the UK so this still just as confusing.</p>

<p>Installed kernel versions: 2.6.32-21 up to 2.6.35.23.</p>
<p>The booting halted with the following error:</p>
<pre><code>init: .: line 61: can't open '/scripts/functions'
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init not tainted
</code></pre>
<p>Only the first one (2.6.32-21) was working up until know.</p>
<p>I asked for help at <a href="http://ubuntuforums.org/showthread.php?t=1630528" rel="nofollow">ubuntuforums.org</a> and i was told to check if there's any problem regarding my graphics card (ATI Radeon).</p>
<p>I uninstalled all the ATI-related packages as well as all the unecessary xserver-xorg-video-* drivers that were installed.</p>
<p>I then rebooted and from then on ALL of the kernels halt with the same error (i.e. it didn't fix the problematic kernels, it just broke the only one that was working...)</p>
<p>Any ideas on what i should try next?</p>
<p>Thanks in advance.</p>

<pre><code>[Errno 30] Read-only file system: '/target/bin'.

<p>Curiously:</p>
<ul>
<li>Windows XP will install to this SSD with no issues</li>
<li>I can install 10.04 to a standard hard drive with no errors.</li>
</ul>
<p>What is happening that is stopping me from installing 10.04 to this drive? I am positive that there is no issue with the SSD (I have two brand new, identical SSDs which both encounter this error.) They are OCZ Vertex II 60gb drives.</p>
<p>I have tried partitioning the drive using gparted on another machine, leaving 5mb free at the start of the drive, and having a single partition for /, and a 1gb swap partition. "Round to cylinders" was unchecked. The partitioning was successful, and the drives can be mounted on my other machine, but the 10.04 installer encounters the same error.</p>
<p>Any suggestions for what to try next would be appreciated, or I'll be stuck with reverting to a HDD!</p>

<p>The problem is that when I change my visual effects from None to Normal, I can no longer drag and drop a window to another workspace using the workspace switcher applet. From what I've read, this is a compiz bug that hasn't been fixed for years.</p>
<p>On the other hand, the problem with using metacity's compositing_manager is that my <kbd>Alt</kbd>+<kbd>Tab</kbd> becomes noticeably slower than the usual. </p>
<p>Is there a way to make things work? Since it seems that the compiz problem is not going to be fixed, I wonder if there's a way to fix my alt+tab with metacity's compositing enabled.</p>

And there are clearly some differences that are very relevant to deploying each.</p>\n\n<hr>\n\n<p>I think the prime consideration and comparison between debian stable and an Ubuntu LTS is security and general package updates.</p>\n\n<p>Debian \"stable\" releases are supported for a year after the next stable release. So if a stable comes out every two years, and you started on a stable release right at its launch, you get three years of updates:</p>\n\n<blockquote>\n <p>The security team tries to support a stable distribution for about one year after the next stable distribution has been released, except when another stable distribution is released within this year. It is not possible to support three distributions; supporting two simultaneously is already difficult enough.</p>\n</blockquote>\n\n<p>You should note that the debian cadence is not guaranteed. Stable releases come out when they're ready. This could mean you get anywhere from 18 months to 18 years of support. This makes it very unpredictable as you won't know when you need to upgrade until you know when the next stable will be finalised.</p>\n\n<p>Compare that to a <a href=\"https://wiki.ubuntu.com/LTS\">Ubuntu LTS release</a>, desktop updates are very similar but for the server applications and kernel, you get a mammoth 5 years of support, regardless of any new LTS releases in that time:</p>\n\n<blockquote>\n <p>A new LTS version is usually released every 2 years. With the v12.04 Long Term Support (LTS) version you get 5 years support for both the Ubuntu Desktop and the Ubuntu Server. There is no extra fee for the LTS version; we make our very best work available to everyone on the same free terms.</p>\n</blockquote>\n\n<p>This means you should be able to deploy the latest LTS on a box and not have to worry about it not getting security updates (for supported packages) for years and years. When you have more than a handful of servers, or just some applications that can't afford any downtime for testing upgrades, or just don't have the time to spend a day/week testing upgrades, Ubuntu has a large advantage over debian.</p>\n",

<p>So the status about 10.10 is unknown. Plus even if LVPM does work, it has the problem of <a href="http://ubuntuforums.org/showthread.php?t=438591" rel="nofollow noreferrer">wiping the partition</a> on which it is going to be installed. </p>
<p>Is there a way to install Ubuntu without using a USB/CD? yes -> WUBI</p>

I think I don't need it, but better to know for sure if it will not
cause some unpredicted behaviour.<br>
Actually my thoughts were:</p>
<ul>
<li>The server never hibernates</li>
<li>If it is swapping one need to think about loadbalancing/traffic shaping, etc...</li>

When you run out of RAM and you have swap enabled, things slow down (sometimes a lot, sometimes just a little bit, depending on what gets shoved in there) but you're able to log in, find the problem and try to fix it.</p>\n\n<p>When you run out of RAM and have no swap, processes die, things stall and a lot of the time your only option is a reboot. But until you do that reboot, things will probably break.</p>\n\n<p>In my world, broken is far worse than slow.</p>\n\n<p>Of course if you find your system is constantly using large portions of swap (it will very often use <em>some</em> just as a way of moving out old cached stuff), you obviously have a problem (\"insert RAM please\"), but having it as a safety net is definitely recommended.</p>\n\n<hr>\n\n<p>In response to the comment from SpamapS:</p>\n\n<p>In the world of \"successful websites\", you have hot failovers, load balancing and other tools that allow a machine to explode and have zero effect on the rest of the site. But that takes a lot of cash. Having redundant hardware isn't economical for most sites, even if they pull in money.</p>\n\n<p>I completely disagree with your comment on uptime. <strong>In a traditional e-commerce set-up if people can't see your site, they <em>can't</em> buy from you.</strong> This isn't just e-commerce, all online commercial interests take a lot more flak if you're down for any sort of period. I know because I host sites and services for companies and run my own sites. Slow = grumpy but Down = fury. Even if you only go down for a minute at a time, if a user sees a \"down-for-maintenance\" notice more than a couple of times, they assume you can't keep the site up.</p>\n\n<p>A slow server is less than ideal but swap isn't there to be run on all the time, it's a last resort to allow things to keep running while you fix them.</p>\n\n<p>You also assume there is only one service running on the machine. Again this might be true if you have megabucks to split out everything but in the real world, things get lumped together. Multiple websites, ssh daemons, ftp servers, email servers, etc. One process leaking into swap might not even effect another service. Without swap, everything has an equal chance of instant, random termination. You have no control over it.</p>\n\n<p>Of course swap isn't the only answer. You need monitoring to alert you when you're out of ram, but just pulling the plug and rebooting isn't the answer for the majority of people. I'm sure this works for whichever multi-national website you're responsible for but for us mere mortals (that make up the majority of the internet), doing that is commercial suicide.</p>\n",

<p>If this helps: I am using NVidia's proprietary, Ubuntu 10.04.</p>

When I boot I get into <code>grub rescue></code>. After some internet reading I concluded that I would have to re-install grub (I was forgotten :$ that I installed Ubuntu via wubi, thought I had it standalone..) and used <a href="http://ubuntuforums.org/showthread.php?t=1014708" rel="nofollow">this tutorial</a>. Now I have a command line grub and am confused about what to do.</p>
<p>My directory structure is as follows: </p>
<pre><code>/dev/sda5 (NTFS)
/boot
/grub
<grubfiles>
/ubuntu
/disks
/boot
/grub
<empty>
/install
/winboot
...
...
</code></pre>
<p>Is it logical that <code>/ubuntu/disks/boot/grub/</code> is empty? I would like to get the bootloader back to being able to choose between windows and linux. Any help appreciated :)</p>
<p><strong>Update</strong>
My problem is kind of solved by installing a standalone Ubuntu 10.10. Now I got my bootloader back correctly, have to go through 3 bootloader screens now to enter Ubuntu 10.04 though ^^</p>

"body": "<p>At first I answered this question to match Lucasmus' situation where he actually had been able to restore the ability to boot already, and had a working grub from a (non-wubi Ubuntu install) on his MBR. Since most people coming here are probably not in that situation, but just getting the grub rescue shell at boot and can't boot Windows or their Wubi install at all, I've remade the instructions for the normal case. The answer for Lucasmus's question was basically to follow what's now steps 2 through 5 below.</p>\n\n<p>This is unfortunately a known bug in Wubi <a href=\"https://bugs.launchpad.net/bugs/610898\" rel=\"nofollow\">https://bugs.launchpad.net/bugs/610898</a>. I've submitted a patch to hopefully prevent future users from having Wubi render their drive completely unbootable but until that or another fix is accepted this is what you need to do (in Wubi) to get Windows and Ubuntu booting and prevent this from happening again:</p>\n\n<p>1: Boot from an Ubuntu LiveCD and run <code>sudo software-properties-gtk -e universe && sudo apt-get update && sudo apt-get install mbr && sudo install-mbr /dev/sda</code>. </p>\n\n<p>If you have more than one hard drive you will need to change <code>/dev/sda</code> in that last command to the drive windows is on. But it will always be a drive, never a partition. So <code>/dev/sdb</code> might be appropriate but <em>never</em> <code>/dev/sdb1</code> (doing the latter could overwrite Window's PBR making it even harder to boot back into windows). </p>\n\n<p>Now you should be able to boot into Windows or your Wubi install like before. If you want to continue using Wubi then follow the next steps to be sure that you don't get into an unbootable situation again.</p>\n\n<p>2: Boot into your Wubi install and run <code>sudo dpkg-reconfigure grub-pc</code> This will bring up some dialogs with questions.</p>\n\n<p>3: For the first question <code>The following Linux command line was extracted from /etc/default/grub or the 'kopt' parameter in GRUB Legacy's menu.lst. Please verify that it is correct, and modify it if necessary.</code> Leave the field at its default (probably blank) and press enter to continue to the next question.</p>\n\n<p>4: For the second question <code>The following string will be used as Linux parameters for the default menu entry but not for the recovery mode.</code> again leave it at the default (probably \"quiet splash\") and press enter to continue</p>\n\n<p>5: This question <code>...GRUB install devices:</code> is the important one. Make sure that you uncheck everything but <code>/dev/loop0</code>. You can check/uncheck an entry with the space bar, and change entries with the arrow keys.</p>\n\n<p><strong>If you press enter before unchecking /dev/sda from this list your computer will become unbootable again.</strong></p>\n\n<p>Now you can safely update/upgrade your Wubi install without worrying about your computer becoming unbootable.</p>\n",

<p>Unfortunately, everything I look at is shackled to its own copy of Windows. I don't believe in paying for something I'm not going to use (unless it's cheaper than any other option).</p>
<p>So far the only thing that really checks the boxes is the <a href="http://www.system76.com/product_info.php?cPath=28&products_id=106" rel="nofollow">Lemur UltraThin from System76</a> but it's a US company and while they do deliver to the UK now, it would likely rack up import taxes, VAT, etc... Paired with an exchange rate that can go either way, and it looks like it could be a bit expensive.</p>
<p>So I'm looking for UK-based options. Around £400. 7-13" screen (as long as it's small). Either running Ubuntu (or something that can be replaced by Ubuntu) or naked. Obviously with good Linux support... And modern hardware that will last a couple of years.</p>

Last friday I had to unplug the tape drives a couple of times.
Today, the devices are "reversed" (nst0 is now nst1).</p>
<p>Is there a way to force the device name, so that nst0 is always assigned to the same drive?
(as in, if nst0 is not plugged in, nst0 will not be assigned to another device.)</p>

When I open a bookmark or enter <code>ssh://user@server</code> in the location bar, Nautilus completely freezes and doesn't recover (edit: same with sftp://). I can kill Nautilus and the desktop will load again. Everything else works as it should. As soon as I try to access a server through ssh, nautilus freezes again.</p>
<p>Nothing was changed on the servers and no updates have been installed on the computer. A reboot doesn't help, either.</p>
<p>I use key-authentication if that is important. I AM being asked for the key-passphrase and then the freeze occurs.</p>
<p>Update: This stopped working while I was using it. I was uploading some files, did something else, and when I got back to upload some more edited files the freezing began. To me this feels like some messed up or incomplete cache files that nautilus still tries to use.</p>

<p>I seem to be constantly running into problems with Flash player freezing crashing, mostly because of running too many flash apps at once (pandora/fantasy apps/youtube/etc). Does using one of these over the other have performance benefits? Or am I confusing myself and it doesn't really matter as they're both the same?</p>

<p>I've been searching high and low for something like this:</p>
<ul>
<li>less than 2kg</li>
<li>hopefully Intel i5 (but negotiable)</li>
<li>NO dvd drive - just don't need it</li>
<li>4G ram</li>
<li>either 7200rpm disk or SSD (ssd preferable)</li>
<li>13 inch screen </li>
<li>not too pricey (MacBook Air is about $1700 AUD)</li>
<li>available in Australia</li>
</ul>
<p>The Dell Inspiron 13z and Lenovo Edge 13 look close, but I've not found anything that says I'm not going to have a fight with compatibility.</p>
<p>The MacBook Air 13 looks like the PERFECT hardware, but I'm afraid it will just be easier to run MacOS than Ubuntu.</p>
<p>I <em>want</em> to stay with Ubuntu, but the MacBook Air is only $1700 so I'm in danger of becoming another apple fanboi if I can't find anything competitive. </p>
<p>Going through all the sites looking for stuff has been a huge waste of time</p>
<ul>
<li>System 76 doesn't deliver to Australia</li>
<li><a href="http://www.linux-laptop.net/" rel="nofollow">http://www.linux-laptop.net/</a> and <a href="http://www.linlap.com/" rel="nofollow">http://www.linlap.com/</a> are hard work and not confidence inspiring</li>
<li><a href="http://www.vgcomputing.com.au/nsintro.html" rel="nofollow">http://www.vgcomputing.com.au/nsintro.html</a> is hard work again, searching for every laptop they say has excellent compatibility on the web to find out what spec it is</li>
<li><a href="http://zareason.com/shop/Strata-Pro-13.html" rel="nofollow">http://zareason.com/shop/Strata-Pro-13.html</a> (at $1345 USD) looks interesting, but I've got no idea how much I'll get stung by customs importing</li>
<li>Dell Inspiron 13z with i5, 4G, 320 7200rpm disk, ATI Mobility Radeon HD5430 - 1GB, Dell Wireless 1501 802.11b/g/n @ $1200 AUD seems like the only competitor but is it compatible? (Dell support offer no opinion - as far as they are concerned they only have 2 models that are certified for ubuntu)</li>
</ul>
<p>Am I worrying too much about the compatibility?
Should I just go with Dell?
Or switch to MacOS?</p>
<p>(It would be good to have a searchable database that had the full machine specs, and compatibility - I'm thinking about building something... but I don't have much time right now...)</p>
<p>Thanks.</p>
<p><strong>UPDATE</strong> I went with a MacBook Air. The price/weight/power was just right. Everything else was either too pricy (i5) or too heavy, or underpowered (SU7300 1.3GHz). Its a pity, because I didn't really want to leave Ubuntu. I'll still run it on my media center and spare (heavy) laptop.</p>

Unlike the preinstalled Windows 7, Ubuntu will not reboot on this computer. Rebooting from Gnome, using the <code>reboot</code> command and SysRq+REISUB all don't work; they end hanging with a blank screen.</p>
<p>I have read that Atom netbooks don't have a keyboard controller and therefore the default reboot method, <code>kbd</code>, won't work. I have actually tried all ten <code>reboot=</code> parameters listed <a href="http://linux.koolsolutions.com/2009/08/04/howto-fix-linux-hangfreeze-during-reboots-and-restarts/">here</a>; none of them work.</p>
<p>I have also tried disabling ACPI with <code>noacpi acpi=off</code> for each one; that didn't help either.</p>
<p>Are there any other things I can try to fix the rebooting problem?</p>

<pre><code>dpkg -l network-manager
</code></pre>
<p>returns the information on the package:</p>

<p>As you can see, it returns <code>0.8.3~git.20101118t223039</code> which is wrong because it truncates the version (I've picked a long one for the purpose of this question). The way I've solved this in the past is to pass a stupidly long COLUMNS argument to make it expand:</p>
<pre><code>COLUMNS=200 dpkg -l network-manager
</code></pre>
<p>which gives me the entire version number, but also a bunch of junk:</p>
<pre><code>Desired=Unknown/Install/Remove/Purge/Hold

</code></pre>
<p>Now I can see the full version number, which is <code>0.8.3~git.20101118t223039.d60a988-0ubuntu1</code>.</p>
<p>I get the feeling that this is not the proper way to find the version number of an installed package.

<p>It's confusing to see that starting OpenOffice by typing ooffice in the terminal is working fine. So that's a workaround for me to use the OpenOffice Writer, but it's no satisfying solution.</p>
<p>When I execute "ooffice -writer" (see comments) I get the following message:</p>
<p>terminate called after throwing an instance of com::sun::star::lang::WrappedTargetRuntimeException' </p>
<p><strong>I figured out that root can start oowriter. So it seems to be a permission problem.</strong> It's a default Ubuntu OpenOffice installation.</p>
<p>How can I fix this?</p>

<p>at the first screen at bootup if I press any key,there is an option to select "try Ubuntu without installing",in this case I go to tryout mode directly... I want this behaviour without pressing any key...</p>

<p>So can someone just tell me how to enable compiz desktop on an Intel i5 based system. This is an Arrandale processor so its got the graphics bit on the processor itself. My system also has a discrete graphics card (Nvidia GT330M - yup its those hybrid graphics combos n- not Optimus). As far as i know the nvidia gpu is not being used since the intel one is enabled and there is no bios route to disable it. The laptop is a Dell Vostro 3700 with bios version A10</p>
<p>I did lotsa google searches about intel compiz, etc but not a single conclusive guide as to how to enable it. so my guess is it should work out of the box. but it doesn't.</p>

Determining CPU usage revealed a \"strange\" state of affairs for `htop` which showed 95% for all three tests.. However, `top` may have been more realistic it reported: no thread option 95%... threads=2 143%... threads=4 212%... So it seems that 1 core = 100%, but `htop` didn't show the extra threads (or at least that's how it looks to me).",

15476 | 1 | 15511 | 2010-11-30T10:05:31.107 | 4 | 16913 | <p>I have an issue with one of our servers running Ubuntu 10.04, it is running BackupPC and collects backups from various machines / servers around the building.</p>
<p>On the 8th minute (12:08, 12:18, 12:28 etc) the backups are transferred to an external hard drive, we have three and rotate one drive for another everyday.</p>
<p>The problem we are having is we are randomly experiencing input / output errors, when this happens you cannot read / write to the drive, it hasn't unmounted so I can <code>cd</code> to the mount point <code>/media/backup1</code>.</p>
<p>The drives are not faulty as it's happening on all of them, so I'm at a loss as to what the problem could be, here is an example of the many errors we get:</p>

</code></pre>
<p><strong>EDIT » Resolved</strong></p>
<p>So it turns out Quamis was right, even though I didn't think it was possible it was actually a problem with the drive. You see we have three drives all formatted to ext2, on two of them we were getting I/O errors frequently, I came back to Quamis' answer and discovered the <code>fsck</code> command, so ran it against the problematic drives:</p>
<pre><code>fsck /dev/sdb1
</code></pre>
<p>This found and fixed a load of problems on the drive, most probably caused by power outages / unsafe removal of drives etc, as the drives are in the xt2 format they aren't journalled and thus aren't protected against such issues.</p>
<p>Drives are now working beautifully, thanks all! :D</p>

<pre><code>ubuntu-server:/home/matt /nfs/matt nfs rw,hard,intr 0 0
ubuntu-server:/home/shared /nfs/shared nfs rw,hard,intr 0 0
</code></pre>
<p>followed by <code>sudo mount /nfs/shared</code>.
(I also needed to add an entry to <code>/etc/hosts</code> so the server name would resolve to ip)</p>

<p><strong>Update 1</strong><br>
This error occurred after I updated my <code>2.6.32-26</code> version kernel and booted directly in Windows. </p>
<p>The <a href="https://askubuntu.com/questions/15515/disk-by-uuid-not-detected-initramfs/15527#15527">rootdelay solution</a> did not work. Is there any chance that my disk's uuid got changed (maybe by windows), I could log in to my Ubuntu earlier but after logging into windows, and rebooting I get this error. As far as backing up is concerned, do I need to even if I have separate home and workspace partitions than Ubuntu installation? </p>
<p><strong>Update 2</strong><br>
The update after which this happened was just an update (no new install) of <code>version 2.6.32-26.</code> So I guess this has something to do with last update of this version of kernel. Also since it was not a new install, no new menu entry was added. By any chance may this be caused because of my <strong>rebooting in Windows</strong> after the kernel update. </p>
<p><strong>Update 3</strong><br>
Installed older kernel by chrooting through live USB, still the same problem with the kernel, so it seems the problem is not due to <em>kernel update</em> after all. </p>
<p>I have faced this problem earlier too but back then, I just considered reinstalling distribution easier (I used to distro switch a lot). But now I had configured it too far and so looking for some last resort. </p>
<p><strong>Update 4</strong><br>
Reinstalled Ubuntu. Configuration was easier this time thanks to separate home and workspace partitions. Even tough I don't need the solution of this problem just now but if you know any possible solution please post here for future benefit. </p>

<p>I'm following the instructions from <a href="http://web.archive.org/web/20080119224658/http://www.trodrigues.net/wiki/linux%3aubuntu%3alexmark_x1290" rel="nofollow">http://www.trodrigues.net/wiki/linux:ubuntu:lexmark_x1290</a> and using the Z600 series driver from Lexmark.</p>
<p><strong>Create a directory named lexmark and unpack the driver:</strong></p>
<pre><code>mkdir lexmark
tar -xvzf CJLZ600LE-CUPS-1.0-1.TAR.gz
</code></pre>
<p><strong>Extract the driver from the install script:</strong></p>
<pre><code>tail -n +143 z600cups-1.0-1.gz.sh > install.tar.gz
</code></pre>
<p><strong>And untar it:</strong></p>
<pre><code>tar -xvzf install.tar.gz
</code></pre>
<p>This generates 2 drivers (<code>z600cups-1.0-1.i386.rpm</code> and <code>z600llpddk-2.0-1.i386.rpm</code>) that then should be converted to <code>.deb</code> files with <code>alien</code> and installed with <code>dpkg</code>, but -as the filenames already indicate- the drivers are for 32-bit systems and not for 64-bit systems. Hence the error: </p>
<pre><code>$ sudo dpkg -i z600cups_1.0-2_i386.deb
dpkg: error processing z600cups_1.0-2_i386.deb (--install):
package architecture (i386) does not match system (amd64)
Errors were encountered while processing: z600cups_1.0-2_i386.deb
</code></pre>
<p>Any idea how I can get this to work?</p>

So 2 days back When I restarted my machine I got 7 options on the Boot Screen instead of 5. Earlier Windows was the 5th Option (I made it default), but now some Memory test is the 5th option (Being Defaulted). How did it automatically happen? I didnt configure or changed anything.</p>

"body": "<p>When the Linux kernel is updated, the older kernel images stick about in case the newer ones are incompatible with your system in some way. There are two parts to each kernel image - the normal one, which you boot up with, and the recovery image, which is why the menu increases by two entries with each update. The number of older kernels doesn't usually go beyond three (plus the respective recovery images, for a total of six images) so the size of your boot menu should be fixed from now on.</p>\n\n<p>You can stop the older ones from appearing by editing your grub menu file, by typing</p>\n\n<pre><code>sudo gedit /boot/grub/menu.lst\n</code></pre>\n\n<p>into a terminal and commenting them out with a <code>#</code> symbol in front of them (look around the file for examples). I assume you know how to do since you were able to set Windows as the default. You can also remove them to free up disk space if you're sure you won't need them.</p>\n\n<p>The safest way, in my mind anyway, to do this is to install <a href=\"http://ubuntu-tweak.com/\" rel=\"nofollow\">Ubuntu Tweak</a>, which contains an option to remove redundant kernel images. It will display a list of the additional images and you just pick the ones you don't want, and the safety comes from the application not displaying the one that is currently loaded.</p>\n\n<p>It's not advisable to get rid of all of them, either by hiding them or removing them, for two reasons. The first is that when you encounter a serious problem (usually related to hardware and usually when it's not working) the best course of action is to boot using a previous kernel image to see if the problem is resolved there. Updates to the kernel can have a nasty habit of breaking parts of one's system. The other reason is that the 'recovery' image in can be quite useful, especially if you forget your password.</p>\n",

<p>When I close my lid on my Lenovo SL500 laptop with in-built webcam, my computer goes on standby. When I start up again the webcam light turns on - for no reason.</p>
<p>I've found a way to make the light turn off again; starting cheese webcam (or probably any other webcam using program) then the light turns off for a second and goes back on, and the program shows camera video. When I close the program the light turns off as well.</p>
<p>Can anybody tell me if my computer is actually turning on the webcam or just the light?
and what can I do to solve this problem?</p>

<p>I am working on a clean install of Ubuntu 10.10 Maverick. I am trying to use vivu.tv's webinar features, but I am consistently getting a connection error. This occurs on both Lucid and Maverick, using both Chrome and Firefox. We were able to test with the support team for vivu.tv, and we confirmed that it worked fine with http tunneling, but broke when they switched to rtmp. (Them using http tunneling is not an option, so I got to get my system to work with rtmp.)</p>
<p>You should be able to replicate this problem by going to this link:</p>
<p><a href="http://vivu.tv/vivuweb/home/featuredarchives/" rel="nofollow">http://vivu.tv/vivuweb/home/featuredarchives/</a></p>
<p>A box will begin a Startup Check, will stall on Connecting to Media Servers, and then will display an error stating that it was unable to connect to the media server.</p>
<p>This is a time sensitive issue for me, as I require access to several archived webinars for an important course I am developing.</p>
<p>Any help?</p>

15570 | 1 | 15643 | 2010-11-30T18:02:19.800 | 29 | 110867 | <p>I have a USB scale, a USB HID. Currently, when it is plugged in, the permissions only allow the superuser to access it. How can I configure udev to let anybody access this device? I have the vendor and product IDs, but I would like to match it based on the HID type instead.</p>
<p>Right now, I'm having trouble finding any existing rule that applies to this (I grepped for "hidraw" in <code>/lib/udev/rules.d</code> and <code>/etc/udev/rules.d</code>, among other things).</p>
